MAUS – Arduino Mouse Jiggler

Arduino‑based, open‑source, tiny, and customizable mouse jiggler with RGB personality.

MAUS is a compact USB device designed to simulate gentle mouse activity and keep your computer awake. Ideal for remote work, long presentations, downloads, or any workflow where screen timeouts are unwelcome. Built around an ATtiny85 and fully programmable with Arduino, MAUS blends practicality with maker freedom.

🖱️ Why MAUS Stands Out

✨ Small in size, mighty in purpose

A pocket‑friendly USB device that gently nudges your cursor to prevent sleep, lock screens, and interruptions. Perfect for presentations, long downloads, and work‑from‑home setups.

🎨 A splash of RGB flair

MAUS features an onboard red LED and a WS2812B RGB LED. Each movement can be paired with subtle or expressive lighting effects, fully customizable via code.

🧠 Open‑source freedom

Firmware, Arduino sketches, and KiCad schematics are fully open source. Modify the behavior, add new features, or integrate MAUS into your own projects.

🇮🇹 Crafted in Italy

Designed and produced by MAKERSUN, with attention to detail and a strong maker mindset.

💡 Plug and play

MAUS ships with Arduino firmware preinstalled. Just plug it into a USB port and it starts working immediately. No drivers, no software installation required.

🎁 Competitive Advantage

Unlike generic plastic or metal plug‑and‑forget mouse jigglers, MAUS gives you real control. RGB lighting, open firmware, hackable hardware, and a clean Arduino development workflow.

You are not just buying a utility device. You are getting a programmable companion with personality.

✨ Tagline

No more sleepy screens. No more endless logins. Just movement… with light. Familiar like a USB stick. Powerful like a tiny programmable board. MAUS: your silent digital sidekick.
